In a large bowl, fully submerge the dry rice noodles in hot tap water (not boiling, just hot to touch). Let them soak for 8-10 minutes. Drain and set aside.

In a wok or large saute pan over high heat, add just half of the cooking oil. When the oil is hot, swirl it around the bottom of the pan and add the shrimp in a single layer. Let cook for 2 minutes. Try not to move the shrimp too much, let them develop a sear and then flip to sear the other side for an additional minute. The shrimp should be half-cooked. Remove the half-cooked shrimp to a bowl and set aside.

Keep the pan on the stove and add the beaten egg to the pan, stirring constantly to fry quickly. Remove cooked egg to the same bowl as the shrimp.

Turn the heat down to medium-low and let the pan cool down a bit. Swirl in the remaining cooking oil. Add the garlic to the pan and stir fry until the garlic becomes fragrant, about 30 seconds. Add the snow peas and bean sprouts and stir fry for another minute. Add the sauce to the pan from the jar. To get every bit of sauce from the jar, add a tablespoon or so of water, close lid, shake jar and pour that into the pan. Add the drained noodles into the pan. Turn the heat back up to medium-high. Stir to combine.

The moment the sauce begins to simmer, add the shrimp and egg back into the pan and stir fry everything until the shrimp are fully cooked through, about another minute. Add optional garnishes and serve immediately.
